Title:
ULTRASONIC-ASSISTED METHOD FOR PREPARING POLYACRYLIC ACID/ATTAPULGITE COMPOSITE THICKENING AGENT
Document Type and Number:
WIPO Patent Application WO/2023/241730
Kind Code:
A1
Abstract:
The present invention belongs to the field of new materials, and particularly disclosed is an ultrasonic-assisted method for preparing a polyacrylic acid/attapulgite composite thickening agent, which method comprises: firstly, dissociating attapulgite rod crystals by utilizing the activation and dispersion effects of ultrasound, and then initiating polymerization under ultrasonic irradiation to realize polymer coating of the dissociated attapulgite, so as to improve the compatibility thereof with a polymer matrix. During the inverse emulsion polymerization process, ultrasonic irradiation is used to replace traditional stirring; in addition, 2-acrylamide-2-methyl-propanesulfonic acid and an acrylic monomer are selected to perform copolymerization, such that the obtained composite thickening agent has good thickening performance and good electrolyte resistance.
